The shape and size of this carabiner makes it great for most uses, from connecting a belay device to your harness or as a connector at the end of a lanyard. The D-shape makes it one of the strongest and lightest locking carabiners Petzl makes.

D-shape has the highest strength-to-weight ratio of all carabiner designs

Keylock system

Available with manual locking system (SCREW-LOCK) or auto-locking systems (BALL-LOCK, TRIACT-LOCK)
